rust-cache

rust-cache Action

The rust-cache action causes several folders to be cached, and sets up sccache as a rustc wrapper so that build artifacts are cached efficiently.

Folders cached:

• ~/.cargo/registry/index/
• ~/.cargo/registry/cache/
• ~/.cargo/git/db/
• ~/.cargo/target/
• ~/.cache/sccache/

Usage

Add the action to any workflow before performing any cargo commands. This alone is sufficient to cause the registry index to be completely cached, as well as all build artifacts which is handled by sccache.

jobs:
  my_job:
    steps:

If you're cargo installing binary tools in any actions, you can also add a --target-dir ~/.cargo/target option to have the full set of build artifacts cached which will speed up installing binaries that are unlikely to have changed as a whole.
